I have cricket broadbrand on admin account, but on guest account when I double click the start up icon it says it needs software from a disc to complete the installation. I don’t get it. I just plugged in the modem and the software was built in. I clicked that everyone gets connection. I called cricket and it says it’s a vista issue. So how do I fix this? How do I get it to where guests can access the interenet too using my broadband modem?
